HEAVY DUTY
HD stands for Heavy Duty. The new WAVE GRENADE HD has 36cm or 24cm of adjustment for better compatibility with our wave sail range. We analyzed the need for more reliable tubes over this increased length and tested a variety of Aluminum specification. We decided on a wall thickness 33% thicker and an increased outside diameter, for the ultimate durability against bending and breaking.

Severne Cyclops RDM Carbon Mast Extension 24+36cm
Severne Cyclops RDM Mast Extension
RIG YOUR SAIL IN UNDER 1 MINUTE
The CYCLOPS extension has a single pulley for rapid loop ‘n go rigging. Simply pass the loop of rope through the tack pulley on the sail and hook it over the single pulley on the extension. A single pull applies full downhaul tension in seconds. All the ropes and pulleys are kept in perfect alignment to eliminate a lot of the friction and makes up for any loss of leverage from less pulleys. A built-in handle negates the need for any tool, and stuff into the downhaul pocket on the sail. Formuline rope is used to further reduce friction and minimize rope wear. Faster, simpler rigging.
- SINGLE LOOP-GO PULLEY
- EFFICIENT PULLEY ALIGNMENT
- NEW STAINLESS STEEL AUTOMATIC COLLAR
- STAINLESS STEEL BUTTON AND MECHANISM

Goya Extension Pro Carbon – RDM
Graceful and rigid. Goya carbon extensions are lighter and stiffer to accept high loads especially on longer extension settings and large sails.
All Goya extensions use the super strong pin and collar system and come with a proven stainless steel power pulley and cleat. The RDM extension comes with a stepped hole layout to minimize weakening the shaft. These extensions offer the best weight to stiffness ratio, light and incredibly strong. Optimal block-to-block geometry and reduced friction are provided by aligning the pulleys of Goya sails to the pulleys of Goya extensions. All Goya extensions come as Universal Pin (Euro) models, designed to be compact and sleek.

Streamlined RDM Windsurfing Mast Extension
Aluminium
Red-line extensions start with custom 32 millimeter, 6061 T-8 “drawn” aluminum tubing. The kind of tubing they use to make aircraft. Our tubing is engineered so that with its large diameter, the wall thickness can be thinner so the overall result is an incredible high strength, to low weight ratio. This formula has been proven with our years of experience. The holes are precision punched, then the tube is red anodized in and out, permanent laser numbered 2 centimeter settings. The adjustment settings are held with a hard anodized aluminum collar tethered with a spectra line to a stainless steel pin. Fail-safe and virtually break proof. Finally we attach our new beefy “Power-Six” super powerful 6:1 downhaul cleat with large diameter pulleys, perpendicular for power, easy rigging and no crossed lines. A tough Dyneema “super downhaul” line is included.
